Abstract: Presently, about 450 different nuclear power plants, partly highly developed, are operating worldwide. Thereby a great contribution to the worldwide current supply is made by nuclear energy. With a capacity amounting to 360 GWI, these nuclear plants meet 17% of the total energy demand. The use of nuclear energy will become more and more important on a longterm basis, if attention is paid to aspects of resource saving, economic efficiency and care of the environment, with special regard to the reduction of CO$_{2}$ emissions. This, however, requires high safety demands concerning the operation of plants, the intermediate storage and the final storage. Several approaches regarding the safety aspects of future nuclear plants are pursued today, The new safety quality has to ensure that radioactive fission products remain within the reactor plant in any case of failure and thus no catastrophic consequences can occur outside the plant. This is for instance provided by the modified German Atomic Law (1994). In the following account, the safety concept and the possibilities of nuclear core meltdown so far as well as their consequences are discussed. Based on this, the safety demands for future power stations are defined and put in concrete terms. Some examples of solutions that have already been realised and which meet the requirement of being without any risk of catastrophe are presented in the following. Having discussed the different concepts of realising a core reactor with new salty requirements, details concerning the proof of the safety behaviour of future nuclear power stations are explained.
